LOCKING AND CONTROLLING MEANS FOR TURNING PLUGS.

Specification of Letters Patent.

Patented Apr. 30, 1912.

Application filed July 8, 1908. Serial No. 442,543.

To all whom it may concern:

Be it known that I, FRED E. YOUNGS, a citizen of the United States, residing at Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Locking and Controlling Means for Turning Plugs, of which the following is a specification, reference being had therein to the accompanying drawmg.

My invention relates to improvements in locking and controlling means for turning plugs.

The object of my invention is to provide a device of this character which is adapted to be readily attached to an automobile. whereby the valve controlling the supply of fuel oil from the tank is locked, the object of which is to prevent any one from using the automobile.

In automobiles, the oil supply generally runs from the back of the machine to the front beneath the hood, and by my improved device this valve operating device or lock is secured to the dashboard, whereby the same is in reach of the operator.

Another object of my invention is to provide a lock and operating mechanism of this character which can be readily attached to any ordinary automobile, and the parts so adjusted that it can be set at an angle or extended as the case might require.

A still further object of my invention is I to provide a more simple, cheap and eifective device of this character.

In the accompanying drawings, Figure 1, is a vertical sectional view of the forward part of an automobile, showing my device applied thereto. Fig. 2, is a vertical, sectional view of the device. Fig. 3, is a vertical, sectional view taken on a line atright angles to Fig. 2. Fig. 4, is a top plan view of Fig. 1. Fig. 5 is a cross sectionon line a2-a: Fig. 3.

Referring now to the drawings, 1 represents the floor of an automobile, and 2 the dash-board, all of which are varied in machines of different characters.

3 represents the oil supply pipe leading from the oil tank, to the engine, and which is always provided with a cock or turning plug whereby the supply of oil may be shut off from the tank and is in ready reach of the operator of the machine. The cock or turning plug is designated by 4, and is of the usual form for controlling the supply through a pipe, although the exterior is changed to suit certain conditions hereinafter more fully described. v

My improved attachment consists of a housing 5 to which is attached the plate or bracket 6 by means of the screw-bolt 7, which passes through the dash-board 2, as will be hereinafter more fully described. IVithin the housing 5 is the lock carrying case 8 which is of a spherical form whereby it may be moved within the housing 5 for setting it at the desired angle. IVithin the case is a rotatable cylinder 9 locked within the housing by the lock 10, and the lock employed would be of the character known as the pin tumbler cylinder lock, and the operation and construction of which need not be further described. The upper end of the cylinder 9 is provided with the wings 11 by means of which the same may be rotated or turned when released by the look through the medium of a suitable key such as is shown at 12. 'The lower end of the cylinder 9 is lengthened out and flattened as indicated at 13, and adapted to fit within a correspondingly shaped recess 14 in the upper end of the block 15. The lower end of the lock housing is drawn inwardly and has the externally screw-threaded boss 15 upon which is'screwed the socket 17. The

said socket is provided with a recess 18 below the lower end of the boss 16 and into which loosely fits anannular flange 19 car'- ried by the block. The block 15 below the flange is provided with a reduced extension 20 to which is rigidly attached the tubular valve operating member 21. The socket at its lower end is provided with an opening 22 through which the tubular member 21 passes, and said opening is of-a size considerably larger than the member 21. Secured within said opening 22 is a downwardlyextending tubular telescoping guard member 23 which passes over a tubular member 24 carried by the turning plug 4, and this protects the valve stem and other operative provide a set screw 25 which is operated from the inside through the opening 26, registering with the screw when the lock or cylinder is turned or opened, and thus pre- 1 vents the parts being separated by a screw driver when the valve is locked in a closed position, and positively prevents the removal of the lock in order to operate the valve without first unlocking the barrel cyl inder. By this construction, it will be seen. f

that when the cylinder 9 is released by the key the same is turned by the wings 11, which in turn operate the block 15 carrying the tube 21 and said tube operates the valve stem of the valve, whereby the oil supply is opened or cut old, as desired.

In order to adjust-ably hold the locking casing or housing within the housing 5, I provide the bracket 5 which is screwed to the dash-board, as indicated at 26. The bracket 6 is provided with a recess 27 into which fits the nut 28, and said nut extends through a hole in the housing 5, and the inner end has a slot 29 across the same, and through which the web of the lock housing passes. This prevents the unscrewing of the nut. The bolt 7 has a round head on the outside of the dash-board, whereby the bolt cannot be unscrewed by a wrench.

The cock or turning plug 4 has the valve proper 30 therein, and has the passage-way 31 therethrough through which the oil passes when it is turned to register with 'the oil supply pipe 3. The housing 4 is extended upwardly, as indicated at 32, and is provided with an off-set portion 33 internally screw-threaded at 34. The plug proper 30 of the cock is provided with a recess 35 into which fits the packing 36. Screwed within the screw-threaded off-set 33-is a cap 37' which has a downwardly-extended portion 38 adapted to compress the packing 36. The plug 30 has its upper end reduced at 39, and the cap 37 has an inwardly-extendmg portlon 40 whereby the plug is further held within the casing. Secured within the upper end of the plug is the stem 42 which 1s of an angular form, and by means of which the plug is turned. The lower end of the tube 21 is drawn inwardly and is made of an angular form, as indicated at 41, whereby the stem is rotated with the tube 21. The upper end otthe cap is provided with the tube 24 which telescopes with the tube 23, and the two form a guard for the valve stem.

In order to prevent the cap 37 from being unscrewed from the valve casing, except when the valve is open, I provide a screw 44 screwed into the valve casing from the inside, and removable only from the inside.

tion. The screw is of such a length that it can be screwed inwardly into the opening 47 and its outer end will be inwardly extended beyond the inner edge of the casing, whereby the cap can be unscrewed.

From the foregoing description it will be seen that I have provided an attachment for an automobile which can be readily adjusted to fit any automobile, and at the same time providing such a lock for the oil sup ply in which the several parts are so locked together that they cannot be separated When the valve is closed.

In order to prevent the couplings 48 and 49 from being uncoupled from the pipe line, I provide the inner edges thereof with the notches 50, and the plug or casing 4-is provided with the pins 51 which extend downwardly and enter said notches, and prevent the couplings from being unscrewed until after the parts held together by the screw 44 are removed, which allows the pins to be moved vertically as clearly shown in Fig. 2

of the drawings.
